Is learning to control a brain-computer interface like learning a motor skill?

In monkeys it behaves much like one. When the decoder was held fixed for days, control improved with practice until the recorded neurons settled into a stable pattern that was recalled quickly the next day and resisted interference, and a second pattern for a different decoder could be learned and kept alongside it. Letting the decoder adapt at the same time made learning faster and still left a stable network for the task. Human systems mostly recalibrate the decoder instead, so the user's own learning carries less of the load there, though it still plays a part.
